That's interesting:
foo# select source from pg_settings where name='log_min_duration_statement';
source
----------
database
foo# alter database foo reset log_min_duration_statement;
ALTER DATABASE
foo# select source from pg_settings where name='log_min_duration_statement';
source
----------
database
Shouldn't the source change to "config file" after the reset?
